Orange/ Matamp

Founded by Cliff Cooper in 1968 the first Orange amps were supplied by a small north of England company called Radio Craft which made a versatile, top-spec 30-watt valve guitar amp - the Matamp Series 2000.  In autumn 1968, Cliff placed an order to  make some 100-watt valve amps for Orange.   Guitars and drums were part of the line up in the 1970s.   In the mid-1990s Cliff licensed the Orange trademark to the Gibson Corporation in America but Orange went back to Cliff’s hands in the late 90s.  Currently made in UK and China.  [Source: Orange ]
